IMPROVEMENT IN BOILER AND STEAM-PIPE CONNECTIONS.

Specification forming part of Letters Patent No. 152,034-, dated J une 1G, 1874; application filed May 13, 1874.

To alt whom it may concern Be it known that I, FRANK D. CHILD, ot' Boston, of the county of Suii'oll; and State of Massachusetts, have invented a new and useful Locomotive-Boiler and Steam-Pipe (Jonnection; and do hereby declare the same to be fully described in the following specification and`represented in the accompanying drawings, of which- Figure l denotes a front elevation, Fig. 2 a side View, and Fig. 3 a transverse and vertical section, of it. Fig. 4 is a front elevation of it, with the cap removed. Fig. 5 is a horizontal section taken through the two lower valveseats; Fig. 6, a horizontal section taken through the upper valve-seat; and Fig. 7 is a vertical section taken through one of the said lower valve-seats. Fig. 8 is a vertical section taken through all the valve-seats.

The object of the invention is the production of a convenient boiler and steam-cock connection for a series of pipes leading to the pumps and the smoke-stack, or to such and the steamgage of a locomotive-engine boiler.

In the drawings, Av denotes the boiler and steam-cock connection, surmounted by a steamgage carrier or supportingstandard, B, all being formed externally as represented. The part A is chambered, and at the middle of its base is furnished with a tubular teat or projection, c, to open into the boiler, to which the part A may be secured by screw-bolts going through tubes b b, arranged within the part A, as shown, and opening through it. The interior of the part A, by means ot partitions, as seen at b b b', Src., is divided into one or more induction-chambers, B', and three separate eduction chambers, C D D', there being a valve-seat, d, in the. partition c, which separates each of the said eduction-chambers from the induction chamber or chambers B. Each induction-chamber is to be complet-ely insulated from the eduction-chamber by a pa-rtition whose portion containing the valve-seat, as shown in the drawings, is parallel to the cap-plate or cover e. From the two eductionchambers D D', or from openings ff in their outerI ends, the pipes that are to convey steam to the supply-pumps are to be led. From another opening, g, leading out of the upper eduction-chamber C, the pipe to go into the smokestack for increasing its draft when the locomotive-en gine is at rest is to be led. The induction-chamber Bf is shown as provided with three discharge-openings, h fi c', the iirst of which is to connect with and open into a pipe to lead to the steam-gage. Such pipe may be provided with a' cock to close communication with the gage or open it, as occasion may require. The openings t' t are intended for the pipes that lead steam to the apparatus for supplying the cylinders with oil. Each valve-seat d is to be furnished with a valve fixed on the end ot a stem to screw into the cap-plate or a suitable stuffing-box applied thereto.

From the above it will be seen that the eduction-ch amber B opens directly into the steamspace ot' the boiler, and consequently becomes charged with steam while there may be any in the boiler. On opening either of the valves or moving it oft' its seat, steam from the eduction-chamber D will escape through the valveseat into the induction-chamber of such valve.

I claim- 1. The locomotive-engine boiler and pipeconnection, substantially as described, consisting ot' the induction-chamber Bf and the series of separate or insulated eduction-chambers O D D, arranged and provided with valve seats d, all essentially as specitied.

2. The steam-gage standard B, combined with the said boiler and pipe-connection A, all being essentially as shown and set forth.v

The tubular teat a and the bolt-fastenin g ltubes b b, arranged and combined, as represented, with the-induction-chamber B and series of separate eduction-chambers C D D',

provided with valve-seats, all being substantially as specified.
